title: [Electrophoretic characterization of glycosaminoglycans during development of the chick embryo skin].
abstract: Glycosaminoglycans extracted by CPC precipitation from chick embryo skin at 9, 12, 15, 18, 21 days of incubation were separated by three different electrophoretic methods on acetate cellulose strips. We observed the presence of Hyaluronic acid, Dermatan Sulfate and Chondroitin-4-Sulfate during the whole period considered and of Heparan Sulfate only after the 9th day. Dermatan Sulfate increases until the 15th day then decreases progressively; on the contrary Hyaluronic acid and Chondroitin-4-Sulfate decrease during days 9 to 15 then increase until hatching. Heparan Sulfate appear the 9th day then increases progressively until hatching.
